Exotica music as we know it was not really invented in the 40's and 50's, but actually had it's start with Debussy, who attended a world fair and was exposed to Javanese gamelan ensembles....and if you go back even further to the time of Mozart, there was a "Turkish" fashion movement that was very popular at the time (accurately demonstrated in the movie "Amadeus"....)

Surf bands also have incorporated classical.
Originally covered by the Avengers VI in the mid 60s
But done here by a modern band. And others have done it too.
